[comp.sys.ibm.pc.hardware] Disk Boot Failure oddity

pv9y@vax5.cit.cornell.edu (10/03/90)

Here's a wierd problem. A friend has a PC-clone (leading Edge model D)
whose hard disk died a while ago. I put in a new 20 meg Seagate and
all was well for a while. Then, all of a sudden, the computer wouldn't
boot and claimed Disk Boot Failure. Booting from the floppy worked
fine and no other errors were noticed in usage. We fixed the problem
once by running PC Tools DiskFix and fixing partition table errors and
then installing new DOS files with the SYS command. Unfortunately, the
fix only worked for a day - the next day the same thing happened so we
tried using SYS again and once again it worked. 

So my question is, how can those invisible files keep getting munged,
if that is indeed what happened? I can run both Norton Disk Doctor and
Diskfix, though my friend is a ways away so it's all over the phone
(and my friend is barely computer literate past using WOrdPerfect). Is
this the sort of thing that is only cured by a low-level format? Other
ideas?  Thanks .... Adam
